Original abstract

Composites are widely used due to their advanced mechanical properties. Particulate composites with polymer matrix were studied with regard to micro-crack propagation in the matrix. A three phase numerical model was created. Linear elastic material properties of particle and matrix were taken from experiment. Using numerical simulations (based on the finite element method) the influence of interphase properties on micro-crack propagation was studied. The results of this paper can contribute to a better understanding of the micro-crack propagation in particulate composites with respect to the interphase.

Czech abstract

Kompozity jsou v dnešní době velice často používané jako konstrukční materiály díky jejich pokročilým vlastnostem. V tomto příspěvky byly studovány kompozitní materiály s polymerní matricí. Vlastnosti jednotlivých fází byly určeny experimentálně a pomocí MKP byly určeny hodnoty součinitelů intenzity napětí, pomocí kterých byl odhadnut směr dalšího šíření trhliny v matrici.
